That is interesting Dave. I put a number of stump with root mass in my pond but they were mostly Osage Orange, and had no problem. But when I refurbished my son's pond, I also put in several stumps but come to think of it I think they were mostly Pin Oak. I never thought anything about it at the time.
But it seems my son's pond has to date not have BG thrive like I think they should have. I don't think the ones we stocked from my pond died, because he did some limited feeding and the fish were there. But it just seems like there was not the explosion of BG fry that I would have expected.
I wonder now if that could been part of the problem? I would think if it is, after a couple of years and flow through of water it would eventually self correct. But I will not put Oak stumps in the bottom of a pond if I ever build another one.
